Preliminary research shows encouraging results with transplantation of retinal cells in patients with blindness caused by retinitis pigmentosa (RP) and age-related macular degeneration (AMD). view more (2008-07-11)
Our Cheatin' Brain: The Brain's Clever Way of Showing Us the World as a Whole
Whether we choose to admit it or not, we all experience memory errors from time to time. Research has suggested that false memory may be a result of having too many other things to remember or perhaps if too much time has passed. However, previous studies have indicated that a specific type of false memory known as "boundary extension"... view more... (2008-10-30)

When your eyes are presented with erotic images in a way that keeps you from becoming aware of them, your brain can still detect and respond to the images according to your gender and sexual orientation. view more (2006-10-27)
Fish really is brain food
Researchers at the University of Bristol have found that mums-to-be who eat oily fish such as sardines and mackerel have children whose visual development is better. This positive association was also seen for breastfeeding. The findings were announced by Dr Cathy Williams, the eye expert on the Children of the 90s project. This study based in... view more...

How do you teach artists and designers to write?
Although highly adept in the visual domain, art and design students often have difficulty putting their ideas down in writing - a theory supported by a recent report* which found that large numbers of art and design students have many of the difficulties with words normally associated with dyslexia. This problem is now being tackled by Writing... view more... (2003-01-22)
Barrow scientists solve 200-year-old scientific debate involving visual illusions
Neuroscientists at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center have discovered a direct link between eye motions and the perception of illusory motion that solves a 200-year-old debate. view more (2008-11-21)
